Differentail or tranny?

[RedGrandprixgt53]

So as im driving on my way to work today, I turn the corner and bam car starts grinding and wont move. I pull over and its leaking tranny fluid from the passenger side of the car to the left of the transmission pan (looking at the front of the car). I have reverse but it wont go in Drive or 123. Could this be the tranny or just the Diff?

Likely you cracked the diff cover and blew out a lot of fluid. Car won't move w/o fluid.

And also could I just replace that part or would i need the whole tranny? It just grinds in drive and park but not reverse

Diff cover which is on pass side cover looks blown off no fluid it all.leaked out and I only have reverse. I have a few chunks of the case and what seems to be half a gear lol

The diff can be replaced.

Pull the passenger side axle. Take the remnants of the cover and diff out. Look at the gear in the trans case. It's the pinion gear

If you see chips like in the below picture, then you should replace the pinion and diff etc. Pinion BTW is the first part that goes into the case.


If the pinion is good, then yes..you can replace the diff and diff cover.
